I was just wondering if anyone can suggest a software I can use to burn an ISO image, but leaving it open so I can add files to it afterwards.

I actually don't know if any software can enable me to do this. This is what I have done so far..

I have a 15 meg AdvanceCD ISO image, which i want to add roms to, I used WinISO to open the ISO and manually added the files to the image and burnt the whole thing, but when the CD boots up, the linux OS can not mount the CD. I do not know of any other way to add the roms this image.

What I would like to do it just add files to the image, but this image is a bootCD with a minimal linux boot and auto runs MAME.
